I just bought a 2001 Maristar 230 with an '03 x30 tower on it.  It has the '05 stock Clarion headunit in it I believe with the 4 stock Clarion interior speakers.  NOTHING ELSE.

Here are my thoughts/plans:

• 2 Tower Speakers:  1) 2 Polk MM651UM speakers - 100w RMS each @ 4ohms - $150 for pair 2)  2 6.5" Krypt Speaker Cans w/ clamps - $170  
• Tower Speaker Amp:  Phoenix Gold Ryval V1502 2-channel (heard really good things about this brand amp from a friend) - 150w RMS x 2-chan. @ 4ohms - $120
• 1 Sub:  Used Rockford Fosgate 12" HE2 - already in box, dual 4ohm voice coil, 400w RMS - $50
• Amp to run 4 stock interior Clarions and sub:  Kicker 08ZX550.3 3-channel - 70w RMS x 2 chan. @ 4ohms (bridge each Class AB channel to 2 interior Clarions) and 210w RMS x 1 chan. @ 4ohms (Class D channel completely devoted to sub) - $180

Specs for stock Clarion interiors are 50w RMS @ 4ohms I believe.

Included prices because I am working on limited funds so consider value.  After tax and s&h, I would be in a little over $700 and a local friend would be installing as a side job.  I am new to the forum so I didn't know if websites for items were ok but are available if interested.  Any and all opinions are desired.

mymc - from reading other threads you seem very knowledgeable and I would really appreciate your thoughts
